Hierarchy Loading Error - new framework

I'm having some problems with the "new" (since BW 7.3) hierarchy framework. It contains a number of segments

Source Segments

Hierarchy header

Header texts

Hierarchy nodes

Node Texts

Target Segments

Hierarchy header

Header description

Hierarchy structure

Texts for text node

Texts for hierarchy level

I have tried to connect various bits (DataSource 0EPM_EMPLOYEE_ORG_HIER; InfoObject 0EPM_EMPID) from SAP's Business Content.I have created 4 different sets of transformation rules for these different segments. I do not have any rules for the "Texts for hierarchy level".

I assume that this is due to the transformation connecting the "Hierarchy nodes" with the "Hierarchy structure".

As you can see the source field ORG_UNIT is not connected to anything. Indeed, I do not know to which target InfoObject it could be connected. For additional information, I have included the source data for "Hierarchy nodes". You can see that there is some data in the column "ORG_UNIT".
